vlpplication filed ehruaiy 2v, 1925. ASerial No. 5,47/f j will be particularly pointed out in the claims following the description.

In the accompanying drawing, Figure'l is a bottom plan view of a portion of a table top and a leaf, the leaf being held in raised position by a device embodying my invention;V

Figure 2` same; l Y v Figure 3 is a transverse section; Figure 4 isa-view similar yto FigureQ showing the leaf dropped; Y

Figure 5 is a. detail elevation of one of the guides with an adjusting device thereon; i Figure 6 is a detail elevation of the stop guide;

Figure 7 the slide.

Referring more speciiically to the drawing, the numeral 1 designates a portion of the top of a table, desk, typewriter stand, or

is a longitudinal -section ofthe similar article having a drop leaf 2 connectedy thereto by hinges 3, a rim 4 being secured to the underside of thetop 1 adjacent the edge thereof as is usual. Angle brackets 5 are secured in the angle defined by the rim and the table top, as shown, to .reenforce the rim at opposite sides of the point lwhere the slide=passes therethrough. Y

Midway between the angle brackets, a=

notch 6 is cutin the upper edge of the rim and a guide bracket 7 is secured to the side' of the rim at said notch. This guide bracket may be secured to either side of the rim and consists, primarily, of a metal plate having openings 8 at-its ends through which screws orfthe like may be passed in the rim to secure the bracket in place, As shown in Figure 3, the bracket is so placed that its upper edge abuts the underside of the table top, and in its upper edge is formedafcentral notch 9, shown most clearly in Figure 5, which registers with the notch 6 in the rim. A tongue 10 rises centrallyfrom the floor of the notch 9 to a pointV about midway the height of the notch, and a lug ll'projects lateraily from the upper extremity of the is a detail perspective view of` tongue, a similar lug 12'projecting from the i bracket below the lug 11, as shown.vv Threaded openings are formed through the 'lugs Y11 and 12 v-in axialy alineinent to receive an ad# justin'g'screw 13, as shown andas will be understood.

The leaf support consists of a'slide14 of .i Inverted U-shape or channel formation in# serted through the notches'6 andfQwith its top or-cross'lw'eb bearing against the bottom side walls of the notch 9, the tongue thereby` iitting within thechannel of the slide sol that the latter -willbe positively guided as it is slide is -iitted a ring 15 which serves asia Vhandle for the slide and also as `a stop tov lprevent 'it'being-pushed entirely through the .of the Y'table top and its side websengaging i between the sides of the tongue 10 and-the l moved in or out. In the outer end of the The bracket 16 consists of a iiatplate having a notch17v in its upper portion through,V which the slide 14 passes, and also having` ears 18 through wliichfastening devices are inserted into the table top. At its innerend, stop lugs-19 project fromthe'sides of the slide to impinge against the inner side of the stop bracket 16, as shown in Iiigurel,Vv and thereby limitthe outward movement "of the slide. y

`When the slide is pushed inward, as shown in Figure 4, the leaf 2 is permitted to swing downward. Iftlie leaf is to be used, it is swungupward andthe slide is drawn out under it to support it as shown in Figures 1 and 2. Should the. leaf not lie perfectly true or flush with'the table top, a few turns of the adjusting screwk 13 will raise orl lower the outer end of the'slide so as to bring the leaf into the proper plane. such proportions that'it may be easily drawn in Vor outwhen desired but isnot apt to be accidentally moved inwardly and prema-l turely drop the leaf. `V`i7hile the slide will firmly Vsupport the leaf when drawn out,V lit'is lightand inexpensive and of such form that' it may be readily stamped from sheet The slide is of.

I claim as new and' desire to secure byl Letters Patent, is

l. The combination with a table top, and a drop leaf hinged thereto,of spaced alined guides on the table top, a slide movable through the guides to support the leaf in raised position, means on the slide to engage the respective guides and limit the movement of the sli-de in either direction, and means on the outer guide to vertically adjust the outer end of the slide.

2j; The combination with a table top,`and a drop leaf hinged thereto, of guide brackets on the under side of the table top having notches in their upper edges. one of the brackets having a tongue rising` centrally from the floor of the netc-h'therein, and a channeled slide mounted through the notches in the brackets and spanning said tongue and adapted when movedl outwardly to support the leaf in raised position. j y

3, The combination with a table top, and a drop leaf hinged thereto, of guide brackets on the under side of the table top having notches in their upper edges, one of the Vbrackets having a tongue rising centrally from the floor of the notch therein', a lateral lugat the upper end of the tongue, a lateral lug below the tongue, a channeled slide mounted through the notches in thebrackets and spanning said tongue and adapted when moved outwardly to support the leaf in raised position, and an adjusting screw threaded through the lugs and bearing upon the slide to vertically adjust the outer end vof the saine.

'a drop leaf hinged thereto, of guides on the under side of the table top, a channeled slide mounted through the guides and adapted to support the leaf in raised position, and a screw mounted on one of the guides and bearing against the slide Within the channel thereof. 1 Y

Inltestimony whereof, I have signed this specilication. e Y
